Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Overview
Affected versions of this package are vulnerable to Out-of-Bounds via the kfd_parse_subtype function. An attacker can access sensitive kernel memory and corrupt kernel topology metadata by supplying a crafted ACPI CRAT table with an oversized subtype length field, leading to out-of-bounds reads during kernel initialization. This can result in leakage of adjacent kernel heap data and potential kernel crashes or panics during amdgpu/KFD bring-up. This is only exploitable if the attacker has control over the firmware-supplied ACPI CRAT contents prior to kernel boot.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
